Maximize life

Use electrode to full life: A fully used SilverLine® electrode will have a pit depth of 2.0 mm. This is deeper than the pit depth for standard copper electrodes. With proper use, the CoolFlow™ nozzle will last 1:1 with the SilverLine electrode.

Properly tighten the shield and protection cap: Make sure the shield is sealed tightly against the nozzle and the protection cap is properly tightened to the torch to prevent leaking.

Purge torch: After each parts-change, purge the torch for at least 30 seconds to remove residual moisture.

Leak check: After purging the torch, make sure all o-ring seals are working as designed.

Adjust shield gas flow: Having the correct shield gas flow provides protection to the nozzle during the cutting process.

Pierce at correct height: Piercing too low causes molten metal (spatter) to hit the nozzle – the most common cause of premature nozzle failure. Piercing too high can cause misfires.

Adjust arc voltage: As the consumables wear, the torch will get closer to the plate. To maintain optimum cutting height, increase arc voltage in 5-volt increments up to 20 volts higher than the initial setting.

Avoid arc stretching: This can occur during rip cutting off the plate or when the leadout is improperly programmed. This shortens consumable life.

Clean the nozzle: Periodically clean the nozzle to remove spatter. This will prevent double arcing which shortens consumable life.
